This is a decklist that I've had for about a year now, never really changed anything in it when new expansions came, since I'm not very good at deckbuilding. With the nerf of Power Word: Shield I decided to change those out for 2 Explosive Sheep.

Deck had a 58% winrate through the course of this last year, with more than 100 games played (I'm not much of a ranked player), does reasonably well against aggro, (probably much better now with the Explosive Sheep in the deck), beats control most of the time, has a really hard time against other combo decks especially mecha'thun warlock.

This deck can heavily depend on draw luck since not getting any deathrattle cards early on like Loot Hoarder can mean a sure defeat. Also drawing Hemet, Jungle Hunter can really swing games in your favor.

If in the mulligan you get a lot of the combo pieces and the matchup could be control, then mulliganing away the quest is a good idea since completing the quest in the middle of doing the combo ruins it.
